PARIS—A man who pledged allegiance to ISIS killed a police captain and his companion in a suburb of the French capital, a slaying authorities suspect was sparked by the extremist group’s calls for followers in the West to carry out attacks.

Paris Prosecutor François Molins identified the suspect as Larossi Abballa, a 25-year-old Frenchman whom police killed after storming the couple’s house and who had been known to authorities for being a radical Islamist, Wall Street Journal reports. Police detained three people with links to him after the attack, Mr. Molins said.

The victims were named as Jean-Baptiste Salvaing, the 42-year-old deputy police chief in the nearby town of Les Mureaux, and Jessica Schneider, 36, an administrative assistant in the police department of another nearby suburb.

The killings are the latest to stoke fears that Islamic State, using a flood of internet propaganda, has become more effective at provoking attacks by people in Europe and the U.S. who have only tenuous links to the group’s command center in Syria. The attack comes days after a man who authorities believe was inspired to act—but not directed—by the extremist group killed 49 people at a gay nightclub in Orlando, Fla., the worse mass shooting in U.S. history.

Abballa, who lived several miles from the victims, was convicted in 2013 of being a member of a French jihadist group that aimed to send fighters to join al Qaeda in Pakistan and Afghanistan. He served two years in jail, where he was known for attempting to preach Islam to other prisoners…

And it continues. These savages need to be eradicated from the face of the earth.

Pure evil-period.

Our hearts and prayers go out to the victims , their families and their friends.
